You can also change the denominator into a constant like this:
Then, in your Average_And_Difference subroutine, you can replace 6 (or the optimum
value that you determined) with the
You can also use one less variable in this program. Notice that the only time the

Instead of the value 6, try dividing the

Run the program and test the Boe-Bot’s ability to exit a dark room with each
denominator value.
Decide what the optimum denominator value is.
Average_And_Difference:
Denominator CON 6
Average_And_Difference:
Make the changes just discussed, and verify that the program still works
correctly.
Average_And_Difference:
variable is used is to temporarily hold the average value, then it gets divided by
average = timeRight + timeLeft / 2
difference = average / 6
RETURN
average = timeRight + timeLeft / 2
difference = average / Denominator
RETURN
difference = timeRight + timeLeft / 2
